" wmDow-sAsa WEIGHT.

Specification of Letters Patent.

. Patented July 24, 1906.

Application filed November 3, 1904. Serial No. 231.179. I

To all whom it may concern: I Be it known that, I, OSWALD F. ZAHN, a citizenoftheUnitedStates,residingatLosAn -geles,-in the county of Los Angeles and State v 5 of California, have invented a new and useful Improvement in Window-Sash Weights, of which the following is a specification. 3 One objectof th s invention is to provide a i window-sash weight which will be of cheap to construction. v

Another object of this invention is to ,pro-

\ vide a] window-sash weight the weight of which can bereadily adjusted.

Another object of the invention is to provide a sash-weight which will conform a proximately to t e sha e of the recess in t e casing therein to the greatest ossible extent. I The accompanying rawings illustrate the so invention.

f Referring to the drawings, Figure .1 is a "vertical section of the-sash-weight. Fig. 2 is adetail section of the ca -plate before application tothe main tubular weight member. 2 5 Fig. 3 is a plan. Fi 4 is an inverted plan of the sash-weight. 1 1 5 is a partial vertical section showing a riiflerent form of sashweight. Fig. 6 1s a perspective view showing another form.

3o The device comprises a casing or shell pref- 'erably formed of a square or rectangular tube 3'. 1, of sheet metal, in each end of which tube is placed a sheet-metal end plate" which is square or rectan ul'ar and conforms to the interior of the tuiular member 1. The top 1 end plate or cap (indicated at 2) is shown in Fig. 2 and is provided with an upwardly-ex tending flange or rim 3 around its edge. The end plate-4 at the bottom or lower end of the 4'9 tubular member 1 is similarly formed with a .downwardly-extending flange 5. These end plates are secured in the tubular member 1 in any suitable manner, preferabl by upsetting or crimping the walls of the tu ular member '45 1 at the ends thereof over the longitudinallyextending flanges 3 and 5 of the plates 2 and 4, respectively, as shown at 8. Each end plate is bent outwardly, so as to ive it an outwardly convex shape and t e flange 6 member consisting of the anlge element 3 or 5 is bent over to conform to t e convexity of the ends thus giving rounded or oblique cor ner that will prevent interference with the walls of the containingqecess; Therounded or convex ends are stronger than a flat end would be.

, so as to take a vantage of the room.

The upper end cap 2 is rovided with means for the attachment of t e sus ending or operating cord, (indicated at 6.) or this purpose the said end plate is preferably slitted transversely and the ortion 7 between the slits bent up to form a ail or strap to receive the re e or cord 6, which is assed under the said 'ail and looped aroun and then tied. The portions of the plate 2 adjacent to and on the outer side 7 of the said slits are preferably bent down to facilitate the passage of the rope under the bail, and the e ges of the bail are bent up for the same purpose and to give a rounded bearing for the rope.

The interior of the shell or tubular member 1 is filled or packed with any suitable weighting material or filling, (indicated at 9,)f0 r example, iron ore, sand, or other cheap substance of the requisite specific gravityand suitable state of division. This filling may be inserted inthe tubular shell 1 after the bottom end plate Ais put in place and while the upper end of the shell is st1ll open. A washer or packing-plate 10, preferably of pasteboard' or similar puncturable material, is placed on top of the filling or packing 9, said plate substantially fitting the interior of the tubular shell 1, so as to prevent the per end plate 2. T e rectangular or square shape of the sash-weight'above described'is.

of advantage in utilizing to the full the space the window-casing recess. The fastening of the end'plates by the above-described expedient of turning .in the walls thereof over the flanges of the-end plates forms a strong and cheap fastening for said plates, and, moreover, gives a smooth external surface. A

In applying the sash-weight if it is found strument can be inserted through one of the slits or openings 13 in the cap or end plate 2 and forced through the plate 10 to uncture same. The weig t is then inverte and the filling materialis allowed to run out through the puncture until the weight of the device is suificiently reduced.

The device may be variously modified. For example," as shown in Fig. 5, the means to be too heavy a screw-driver or other infor attachment of the suspending or operat- I ing rope may consist of an eye 11, fastened to the top plate, (indicated at 12,) said plate being in this case similar to the cap-plate above described, but without the bail. No specific claim. is made in this application to theform to the top end. plate 1.6 and further bent at its center, as shown at 17, to receive the rope,

the, ends being bent up or flanged, as at 18,

and extending within the flanges 19 oi the top end plate and the ends 2010f the shell 21, being bent over these flange arts to fasten the Whole together. The en plate 16 is of metal sulficiently thin to be punctured, as'by a screw-driver, for the purpose set forth.

My invention is not limited to the use of a rectangular shell, as it may be round, if desired, as shown in Fig. 6.

Wlmt .l claim is 1. A sash weight comprising a shell formed oi'- a tube and end plates in said tube, the ends of the tube being bent over said end plates to fasten the plates in the tube, and filling Ina terial in said shell.

, within the shell over said filling.

A saslnweight comprising a sheetnnetal shell formed of a tube with end plates and having one end plate slitted and bent to form ap Ipttaching-hail, and filling Within said s e e. A sashsweight comprisin a sheet-metal shell, filling within said shell, and a puncturable plate above said filling, said shellhaving" its end slitted and bent to form an attaching-bail and also to form openings for access to said puncturable plate.

5. A sash-Weight comprisinga sheet-rnetal shell formed of a tube, close at the lower end, a punctnrable closure-plate at the upper end of said tube, a filling in said tube, anda bail over said plate.

6. A sash-weight comprising a sheetmetal shell closed at the lower end and having -a slitted plate at the upper end, a bail at the upplpr end of said shell and a filling in the shev 7. A shell having inbent ends, a filling in the shell, means retained by the inherit ends for holding the filIing and means-held byione of" the inbent ends for holding a cord.

In testimony whereof I have hereunto set my hand, at Los Angeles, California, this-ZZth day of October, 1904.
